Data Set Overview :  This dataset contains data generated by MIRO during the Cruise-2 mission phase of Rosetta. In fact, these data consist almost entirely of observations of Comet 9P/TEMPEL 1 (1867 G1) before, during and after the planned collision of the Deep Impact mission impactor spacecraft with that comet in July 2005.  Author List :  The author list in the CITATION_DESC includes only those persons who worked on preparing this archive dataset for delivery. The full list of all persons involved in the MIRO experiment is (taken from the GULKISETAL2007 reference): S. Gulkis, Frerking, M., Crovisier, J., Beaudin, G., Hartogh, P., Encrenaz, P., Koch, T., Kahn, C., Salinas, Y., Nowicki, R., Irigoyen, R., Janssen, M., Stek, P., Hofstadter, M., Allen, M., Backus, C., Kamp, L., Jarchow, C., Steinmetz, E., Deschamps, A., Krieg, J., Gheudin, M., Bockelee-Morvan, D., Biver, N., Encrenaz, T., Despois, D., Ip, W., Lellouch, E., Mann, I., Muhleman, D., Rauer, H., Schloerb, P., and Spilker, T.  Geometry Information :  The MIRO data file labels contain vectors specifying the position of the Sun and Target body relative to the spacecraft and the velocity of the Target body relative to the spacecraft. The values of the keywords SC_SUN_POSITION_VECTOR, SC_TARGET_POSITION_VECTOR and SC_TARGET_VELOCITY_VECTOR are related to the ECLIPJ2000 reference frame. The values of SUB_SPACECRAFT_LATITUDE and SUB_SPACECRAFT_LONGITUDE are northern latitude and eastern longitude in the standard planetocentric IAU  frame. All values are computed for the the midpoint of the observations. Distances are given in , velocities in , angles in .  This information was obtained using the following NAIF/SPICE kernel files: ORHR_______________00031.BSP TEMPEL1-9P-DI-P.BSP de405s.bsp  The vectors were retrieved using the NAIF call SPKEZ() with a correction for one-way light time and stellar aberration using a Newtonian formulation.

These data were not processed in any way other than being decommutated from the raw telemetry stream, so no processing errors are expected. For a discussion of the reliability of the MIRO instrument itself, see the documentation included with this and subsequent mission archives.
